Ls swap....

[matthew31490]

I'm looking at swaping a ls motor from a 91 integra into my 94 civic coupe, now the question is, will it fit, if it will do i have to take out the A/C or anything?

Itll fit but it will be too much work .

The 91 engine is OBD0 , your car is OBD1 so the wiring is totally different.

The 91 Transmission is CABLE operated, your car is HYDRAULIC

THe mounts are totally different

Shift linkage is totally different

You are better off finding a OBD1 engine from a 94+ Integra

ac from the 91 is not compatible as neither are the lines. would have to change intake,injectors,dizzy use and extend your harness in a cpl places and i cant remember if alternator plugs are diffrent.also get 94 up tegra mounts and a hydro to cable conversion, the 91 shift linkage worked on mine. also i dont know how new this is to some but a civic ac compressor will fit but you have to use a crv bracket and modify you ac lines CAREFULLY...may have to change crank pully to 94 up and power stirring line to rack too as civic is too short! OR JUST GET OBD1 LS 94-95 OR UP! ITS SOOOO MUCH EASIER, MORE LIKE PLUG N PLAY...
